The Hog Wild Mud Run, an obstacle-filled race with ropes and slides, is Saturday at 2441 Kirkland Road in Dover. Races begin at 8:30 a.m. and run every half-hour through 12:30 p.m.

It's not called a mud run for nothing. The 5K race includes more than 25 obstacles, including many that feature mud as a chief component. One is aptly termed the "farmer's surprise" (no need to elaborate). Another is the "slippery slope," in which racers try to climb a mud-slathered hillside out of a creek.

The highlight is the so-called "kiss of death" in which participants "kiss the ground," or crawl on their stomach along a mud path as barbed wire and live electrical wires hover inches above.

Costumes are encouraged. Every runner of legal drinking age gets a free beer at the finish line and a shirt and medal.

Participants can register on the same day for $99. You must be at least 14 years old. A separate free race, however, will be offered for children 13 and under. Visit hogwildmudrun.com.
